Thirsty for RV adventures? Adding a portable solar panel to your RV might just be the next best upgrade your RV needs. Solar has the power to give you more freedom to explore uncharted territories without having to worry about finding a campsite with a hookup.

You have a generator you say? You may still need to install a portable solar panel to get the most out of your off-grid adventures as solar is less invasive than a generator. And while getting a solar panel kit may seem like a daunting task, it really isn’t if you know what to look for.

UNDERSTANDING PORTABLE SOLAR PANELS

So, you’re considering adding a portable solar panel kit to your RV? That’s one of the best investments you can make for your RV and yourself.  Let’s take a look at some things you need to know and consider before you take the plunge.


Why you need solar power

solar panel

Solar panels are a very ingenious system that converts solar energy into electrical energy. That electrical energy then gets stored in your batteries. But why would you need solar since most RV parks offer excellent amenities that include power hookups?

There are two main reasons why solar power is something every RVer should consider.

The first is that solar is one of the best ways to recharge your RV’s batteries. It provides a slow, steady charge that actually helps prolong the life of your batteries. That’s good news to anyone who owns an RV, 12-volt marine/deep-cell batteries are a big expense.

The second and probably most important reason you need to consider solar power is that it is a green power source – and it’s unlimited. If you love enjoying the best that nature has, go for solar because it doesn’t leave any footprint on the beautiful parks you want to explore. And the fact that it’s green means it’s also quiet. So there’s no scaring away the beautiful wildlife you want to enjoy. This is a stark contrast when you compare solar to noisy generators that burn fossil fuel.


How a portable solar panel works

Portable solar panels convert sunlight into electricity. When the sunlight hits the panels, it gets converted into an electric current. The electric current feeds into a charge controller. That is a critical component of your portable solar panel kit as it controls the amount of current that goes to your battery. The batteries store the current and release it as DC. The DC is then converted into AC by an inverter.

It's a simple system that produces tremendous results.

PICKING THE RIGHT SOLAR PANEL SIZE

Portable solar panels come in different sizes that supply different amounts of power to your personal electric grid in the RV. The size of the portable solar panel that will be best suited for your RV needs to support the appliances you usually run in your RV.


One simple way to determine the size of the panel you need is to monitor your average battery usage on a typical day. Most RVs have a voltage meter to help you identify how much battery you use. Once you know your usage, it can guide your decision as to what size panel you need. For example, if you run a 100Ah battery bank and you use 50 percent in two days, it means you consume 25Ah a day. You will then need a panel big enough to produce at least that much.


To put it in perspective, if your solar panel is rated 100 Watts and you use it to charge a 12V battery, it will produce 8.33 amps (Watts/voltage = amps). If your battery is rated 100Ahr and it is 50% discharged, it will take your solar panel six hours to make it back to full capacity (Amp hours/amp).


This simple calculation will help you determine the most suitable portable solar panel for you. Not so complicated after all, is it?


A Primer on the Two Types of Solar Panels

One thing you need to know before you jump and grab the nearest portable solar panel is that not all solar panels are the same. Besides the size and output factor, there are the types of panels themselves. While there are many different types of solar panels, there are two that feature the most in portable solar panels.


Mono-Crystalline solar panels

MONO CRYSTALLINE SOLAR PANELS

Mono-Crystalline solar panels feature a single continuous crystal structure. They are easily recognizable by their uniform coloration and uniform look. That is an indicator of high-purity silicon.

Their biggest advantage is that they have a higher level of effectiveness when it comes to converting solar energy into electrical energy. Their efficiency rating is between 15 and 20 percent. However, because of the higher purity and more complex method of producing them, they are more expensive.

Poly-Crystalline solar panels

Poly-Crystalline solar panels, on the other hand, are made up of many square shaped silicon cells. Manufacturers make them by pouring raw silicone into a square mold. The silicon is then cooled and then cut into squares that are joined together to make a panel. This type of panel features a checkered design.

The biggest advantages of poly-crystalline panels are that they are cheaper and generally have a longer lifespan. However, they have a big disadvantage in that they are less efficient in converting solar energy into electrical energy. Their efficiency rating is 13 to 16 percent.  And you will notice the difference on cloudy days.

GETTING A PORTABLE SOLAR PANEL FOR YOUR RV -- YOUR QUESTIONS ANSWERED

Still considering getting a portable solar panel but not sure since you still have some unanswered questions? Well, let’s answer those questions for you then, shall we? That will help you make an informed decision you won’t regret.


HOW LONG CAN I GO RUNNING ON SOLAR?

Solar panels are a way of creating electricity from the sun. They don't store electricity nor do they supply your appliances directly. It's your batteries that determine how long you can go without needing another charge as they are the ones that store the electricity. That is why it we recommend that you use deep cycle batteries as they are designed to store more electricity and only discharge the amount needed. They also have the advantage of being able to withstand more charge and discharge cycles than your normal starter battery, giving them a longer lifespan.


But the short version of the story is that as long as there’s sunlight, you can harvest solar power and convert it into electricity.


HOW MUCH SHOULD I EXPECT TO SPEND ON A PORTABLE SOLAR PANEL?

The amount of money you spend on a portable solar panel kit will depend on the size and output of the solar panel kit as well as the manufacturer. However, portable solar panel kits run the gamut from $100 to $1000.
